Composition of Triterpenoids in <i>Inonotus obliquus</i> and Their Anti-Proliferative Activity on Cancer Cell Lines
The objective of this study was to determine the composition of triterpenoids in the extracts from the inner and outer parts of <i>Inonotus obliquus</i> and to evaluate their anti-proliferative activity against cancer cell lines (HT-29, AGS, MCF-7, and PC3). Inner and outer parts of <...

| description | The objective of this study was to determine the composition of triterpenoids in the extracts from the inner and outer parts of <i>Inonotus obliquus</i> and to evaluate their anti-proliferative activity against cancer cell lines (HT-29, AGS, MCF-7, and PC3). Inner and outer parts of <i>I. obliquus</i> were extracted with 80% methanol for 24 h. The extract was fractionated by Diaion HP-20 resin to obtain the triterpenoid fraction. Composition of triterpenoids in the fraction was analyzed by HPLC and LC-ESI-MS. Anti-proliferative activity was evaluated by MTT assay against cancer cell lines. Inotodiol and trametenolic acid were major triterpenoids in both of the inner and outer parts of <i>I. obliquus</i>. Inotodiol in triterpenoid fractions from the inner and outer parts of <i>I. obliquus</i> was 153.9 ± 15.4 mg/g (dry basis (db)) and 194.1 ± 11.5 mg/g, respectively. Trametenolic acid in triterpenoid fractions from the inner and outer parts of <i>I. obliquus</i> was 94.5 ± 9.15 mg/g (db) and 106.3 ± 8.23 mg/g, respectively. Triterpenoids in the outer part were significantly higher than those in the inner part. Anti-proliferative activity of the triterpenoid fraction from the outer part against AGS, MCF-7, and PC3 was also significantly higher than that of the inner part. |
